Abstract
A sealing arrangement for sealing around a turbine or compressor blade includes casing segments having sealing faces for abutting with opposing sealing faces of circumferentially adjacent casing segments along joints between the segments. The sealing faces on adjacent segments are forced into contact with each other by rotation of each casing segment about a mounting pin. To reduce radial leakage, a sealing plate is provided.
Claims8
In an axial fluid flow turbomachine, a casing assembly comprising:
- a plurality of casing segments arranged in circumferential sequence, wherein circumferentially adjacent casing segments abut each other along generally radially extending joints, each casing segment having circumferentially opposed ends and each of its opposed ends comprising at least one sealing face for abutting with a corresponding sealing face on a circumferentially adjacent segment, each casing segment being mounted for limited pivoting movement about a pivot point, whereby pivoting movement of the casing segments causes the sealing faces to come into sealing contact with each other.
